Central Maine Power is moving forward with construction of a 345,000 volt substation in Kennebunk.
It will cost roughly 30 million dollars and is one of five such substations the company is building under the Maine Power Reliability Program.
Construction began this month in Kennebunk.
CMP says the project will help stabilize the grid and allow for future expansion.
CMP and its parent company, Iber-drola USA, are spending more than 500-million dollars upgrading the power grid... Like last month when they set up power lines spanning the Penobscot river.
The project aims to double the capacity of the backbone of the state's power grid by 2015. All told, there will be 440 miles of new transmission lines in addition to the new substations.
